Biblion: The Boundless Library

Free
The word "biblion" was used in the Middle Ages to describe collections made from fragments of ancient texts. As such, it’s appropriate that the New York Public Library’s iPad app, which draws from tens of thousands of fragments scattered across hundreds of boxes of materials, bears the moniker. The smartly designed and informative Biblion: The Boundless Encyclopedia app focuses on the 1939-40 World's Fair, but even non-enthusiasts can appreciate the history presented. Here’s hoping for a broader topic range in the near future.
